Why hasn't the black list GUI been improved yet?

[Geryth]

First, SE did implement a limit on the number of say/yell/shout/tell messages a character can send per second in 2.3

Then those rascally RMT spammers have easily circumvented that limitation because RMT spam is as worse as it ever has been right now. And I get that that's part of the challenge - they will continue to find ways to get around the restrictions that SE puts in place, and SE has to implement solutions that 1) Stop RMT spammers and 2) Make sure the impact of those measures is as minimal as possible on players. All the more reason why I would like them to make the black list easier to use.
